不完全区组设计中区组间与区组内合并估计的精确方差AI 解读

This article presents methods for evaluating exact variance of combined inter- and intra-block estimates of treatment effects in incomplete block designs. The results are valid for all incomplete block designs and hold for a wide class of combined estimates including most in the literature. Tables of exact variance for some estimates are presented for some balanced designs and for some partially balanced designs.

混杂析因设计中一致更优的组合估计量AI 解读

Many confounded factorial arrangements have the property of obtaining the same precision for any component of a particular main effect or interaction. A procedure for recovery of inter-block information developed by the author (Ann. Math. Statist 1964) is applied to such designs to obtain combined estimators having smaller variance than the corresponding intra-block estimators for all values of the inter and intrablock variances. The procedure has been illustrated for a…
